I may be a bit confused on how CloneCD works, or the concept of a 1-to-1 copy of a disc. And this may have been answered before, but... If CloneCD makes exact, bit-for-bit copies of the source disc, why are there even any settings? Why, for example, can I decide whether CloneCD should read subchannel data? Or have any digital audio extraction "quality" options? Any help would be appreciated. CloneCD is a great program, by the way, keep up the great work everyone. EDIT: I mean this from a disc-reading standpoint. It makes sense to me that, when making a disc-image, it would be appropriate for that image to have every single bit from the original disc on there. Obviously there would need to be different write settings to determine what would be written and what wouldn't, how fast it would be written, etc.
